Torsion Testing Tester

Universal Torsion testing machines are essential tools for measuring the torque and mechanical properties of materials and components..Torsion testing machines can be equipped with various accessories to test a wide range of materials, including springs, specimens, wires, tubes, bars, and chains. These machines are ideal for testing both left-hand and right-hand torsion, making them highly adaptable.

Applicable standards:

GB/T 239.1-2012 "Metal materials wire Part I unidirectional torsion test method"

GB/T 239.2-2012 "Metal materials wire Part II Bidirectional torsion test method"

ISO 7800:2003 "Test method for unidirectional torsion of metal wires"

ISO 9649:1990 Test method for bidirectional torsion of metal wires

Product Advantages:

Evaluates Torsional Ductility: Directly measures the wire's ability to withstand twisting before fracture.

Standardized Testing: Enables testing according to widely recognized national and international standards.

Reveals Defects: Torsional stress can highlight material imperfections or inconsistencies not apparent under other tests.

Supports Quality Control: Provides a reliable method for ensuring consistent wire quality.

Versatile: Can perform both unidirectional and bidirectional torsion tests.

Controlled Parameters: Allows for precise control of twisting speed and specimen length for repeatable results.

Test principle:

Unidirectional torsion: The sample rotates 360 degrees evenly around its axis in one direction as a single torsion to the specified number of times or the sample breaks.

Two-way torsion: the sample rotates 360 degrees evenly around its axis in one direction as a torsion to the specified number of times, and then rotates the same number of times in the opposite direction or the sample breaks.

Main parameters:

1. clamping metal wire diameter range: 3.0≤d(D)<5.0

2. the space between the two fixtures: 500mm

3. Clamp range: 3.0-5.0mm

4. twisting speed: 30. 60r/min

5. Power supply: AC220V 50Hz

6. Noise: <70 dB(A)

Types of Testing

Torsion Testing: These machines can perform precise torsion tests, measuring the twisting behavior of materials and components under controlled conditions, both for right-hand and left-hand torsion.

Breakage Testing: Torsiometers are capable of conducting breakage tests, helping to evaluate the maximum torsional strength of materials and components until failure occurs.

Fatigue Testing: In addition to static testing, these machines can carry out fatigue tests, which simulate long-term torsional stress and provide data on how materials or components perform over time under cyclic loads.
